Don't forget the abuse and rape of civilians by the Israeli army.

I would really like to see a study on that. Take a color then slowly remove the contrast and ask when the change is discernible. Take a color then slowly transition to another color and ask the same question. Maybe do that with a few hundred people of both sexes and record the differences.

But it'll have to take into account where people are from. In Northern countries for example, it wouldn't surprise me if the difference between blues and whites is much more prominent than reds (snow vs not snow). Or for those living in the jungle all their lives, or those living in cities all their lives, and so on. I'm sure there'll be obvious differences depending on origin and sex.

In the brain there are high concentrations of male sex hormone (androgen) receptors throughout cerebral cortex, especially in the visual cortex which is responsible for processing images. Androgens are also responsible for controlling the development of neurons in the visual cortex during embryogenesis

Probably not. This happens during very early stages of development. Transitioning shouldn't have an impact, but I don't know if research has been done on that.

Time to smoke one.

Read my edit. Also, not every sport is about strength. Additionally, the are other ways to split than just by sex and gender.

Again, like many others missed, the proposal isn't "NO MORE SEGREGATION!". It's to let people compete against each other regardless of sex. I'd prefer it as a default, but it doesn't preclude voluntary segregation.

Until we stop caring about only letting/finding/supporting/producing the best of the best, its an incredibly bad idea to ignore the many sport specific disadvantage biology plays in competition

And with this too, I disagree. If you've done sports, you'll know the feeling of thinking you're the best and then meeting a stronger opponent. For some, it will be demoralising, but for others it's a stimulus. It also lets you learn more about the sport, what is possible, and in certain sports also develop techniques and tactics against opponents with greater values in different attributes.

Evolution happens faster under pressure and competing against better opponents is the best pressure there is. That's how you get the best of the best. You get out of your safe zone.

Also, again for you too, the suggestion is not "no more segregation ever"! You can read my edit.

First of all, heavy weight men =/= heavy weight women at the moment. The kg's aren't the same (men start at 90kg and women 80kg or something?). Second, Mike Tyson beat the shit out of fellow men. Are you going to set the bar for being a man at Mike Tyson? Every guy he beat was actually a woman?

I can't find how much Mike Tyson weighed for every of his fights. This says 99kgs. The heaviest woman I could find (why doesn't a DB exist to sort by kgs?) is Danielle Perkins at 88kg. That's 10kg of difference. No way they're even in the same class unless you leave it open ended. The weight classes would probably have to be redistributed and a new one added. Once a woman gets as heavy as Mike, she could compete against him.

No, you don't. You haven't seen it yet. Nor do you know how 100 or 1000 such matches would end.

It's also fine if you don't want to see it. No one is going to force you too.

What a nonstupid answer. I congratulate you on being so articulate.

OK, I'll just add an edit to the description, but for you too: the suggestion isn't to force desegregation. It's to allow it. Someone else made a better suggestion: segregate by attributes specific to the sport. In boxing it's weight class, in basketball it could be height, in biking it could even be doped and non doped. Sex and gender need not be the very first thing to segregate by.

Finally, the option to compete together should still be the default, IMO. Some people probably would like to join a mixed team, but simply can't because it isn't allowed. For example if basketball were segregated by height, some shorter players would maybe like to play in the mixed team regardless (maybe they hit a skill ceiling in their league, maybe they don't like the idea of segregation, etc.).

Does that answer your question?

No, it doesn't answer if it'll be the same for all sports. As others have pointed out archery, shooting, curling, and other sports have men an women competing either separate or together and women can compete at the same level.

As for football, yes, there's a good chance there'll be stark differences, but as I pointed out in another comment, not every sport is about raw strength. And, competing against stronger opponents can also raise your ceiling. How far is of course yet to be seen because we don't have mixed leagues.

And again, the suggestion isn't "NO MORE SEGREGATION EVER" it's "should we let them compete against each other". That means there'll be a mixed and segregated league. Maybe even, as somebody else suggested, the segregations wouldn't always be immediately by sex or gender, but by attributes that make sense in that sport e.g weight, muscle mass, height, skill, and so on.

Yes, that's a sport where segregation makes sense. But the suggestion isn't to force desegregation, it's to to let all genders compete against each other.
